Fix typos in the Include directory (GH-28745)

bpo-40116: Add insertion order bit-vector to dict values to allow dicts to share keys more freely. (GH-28520)

bpo-45020: Identify which frozen modules are actually aliases. (gh-28655)

2021-10-05T17:26:37+00:00

In the list of generated frozen modules at the top of Tools/scripts/freeze_modules.py, you will find that some of the modules have a different name than the module (or .py file) that is actually frozen. Let's call each case an "alias". Aliases do not come into play until we get to the (generated) list of modules in Python/frozen.c. (The tool for freezing modules, Programs/_freeze_module, is only concerned with the source file, not the module it will be used for.)

Knowledge of which frozen modules are aliases (and the identity of the original module) normally isn't important. However, this information is valuable when we go to set __file__ on frozen stdlib modules. This change updates Tools/scripts/freeze_modules.py to map aliases to the original module name (or None if not a stdlib module) in Python/frozen.c. We also add a helper function in Python/import.c to look up a frozen module's alias and add the result of that function to the frozen info returned from find_frozen().

bpo-45211: Remember the stdlib dir during startup. (gh-28586)

2021-09-28T18:18:28+00:00

During runtime startup we figure out the stdlib dir but currently throw that information away. This change preserves it and exposes it via PyConfig.stdlib_dir, _Py_GetStdlibDir(), and sys._stdlib_dir.

bpo-45211: Move helpers from getpath.c to internal API. (gh-28550)

2021-09-27T16:00:32+00:00

This accomplishes 2 things:

* consolidates some common code between getpath.c and getpathp.c
* makes the helpers available to code in other files

FWIW, the signature of the join_relfile() function (in fileutils.c) intentionally mirrors that of Windows' PathCchCombineEx().

Note that this change is mostly moving code around. No behavior is meant to change.

bpo-45061: Detect refcount bug on empty tuple singleton (GH-28503)

2021-09-21T21:04:34+00:00

Detect refcount bugs in C extensions when the empty tuple singleton
is destroyed by mistake.

Add the _Py_FatalRefcountErrorFunc() function.

bpo-45020: Add -X frozen_modules=[on|off] to explicitly control use of frozen modules. (gh-28320)

2021-09-14T23:31:45+00:00

Currently we freeze several modules into the runtime. For each of these modules it is essential to bootstrapping the runtime that they be frozen. Any other stdlib module that we later freeze into the runtime is not essential. We can just as well import from the .py file.  This PR lets users explicitly choose which should be used, with the new "-X frozen_modules=[on|off]" CLI flag. The default is "off" for now.

bpo-44945: Specialize BINARY_ADD (GH-27967)

bpo-44990: Change layout of evaluation frames. "Layout B" (GH-27933)

2021-08-25T12:44:20+00:00

Places the locals between the specials and stack. This is the more "natural" layout for a C struct, makes the code simpler and gives a slight speedup (~1%)
